One important case that is not mentioned in the article is Eon-Net v. Flagstar Bancorp. And you may want to know what happened in that case because it was a bad day for non-practicing entities, that is, for patent trolls.

Eon-Net is a patent holding company that, with its related entities, had filed over 100 lawsuits against many companies for patent infringement. In most cases, the companies settled for between $25,000 and $75,000 rather than going through the expense of a lawsuit, something which could easily exceed $1,000,000. Flagstar Bancorp, however, decided to fight and spent over $600,000 to litigate the case, an amount that would have been substantially more had the district court allowed full discovery.

To the surprise of many, the court found in favor of Flagstar,

… Eon-Net’s case against Flagstar had “indicia of extortion” because it was part of Eon-Net’s history of filing nearly identical patent infringement complaints against a plethora of diverse defendants, where Eon-Net followed each filing with a demand for a quick settlement at a price far lower than the cost to defend the litigation.

The court went on to state that Eon-Net “acted in bad faith by exploiting the high cost to defend complex litigation to extract a nuisance value settlement”, that cases like theirs are meritless, and that as a non-practicing entity (i.e. troll) Eon-Net faced little risk in filing lawsuits; they faced no business risk, were generally immune to counterclaims, antitrust, and unfair competition claims.

For their legally baseless infringement allegations, the Court of Appeals for the Federal Circuit affirmed the district court’s decision to impose Rule 11 sanctions against Eon-Net.

What does that mean? It means the court may impose monetary penalties which may include awarding reasonable expenses, including attorney’s fees, to the prevailing party (in this case, Flagstar).

And it means a potentially very bad decision for trolls who now might want to reconsider their strategy of filing a barrage of lawsuits.
